Y., A CORPORATION OF NEW YORK.

Application filed July 19, 1921. Serial' No.. 455,931.

To all whom it may concern.

Be it known that I. LOUIS L. ANsART, a citizen of the United States,residing. in borough of the Bronx, in the county of the BronX,-city andState of New York, have invented certain new and useful Improvements inCombined Typewriting and Com:

puting Machines, of which the'following 1's a specification.

This invention relates to-combined typevwriting and computing machines,and is in the nature of an improvement on the application of FrederickA. Hart, Serial No. (365,315, filed December 12, 1911 (now Patent N 0.1,388,257, dated August 23, 1921).

In said application, provision is made of means whereby, after typingnumbers in diffcrent columns and registering the totals a result ortotal obtained from computing the same in a register or totalizer,automatic. printing of such may be effected in a column reserved for thetotal, the mechanism being rendered effective for such automatic typingby proper setting of a manually operable member. The printing of suchtotal, how-- ever, is accompanied by the operation ofindcxing the same,a result which is not-desired, and the indexing mechanism must berestored to normal condition before performing other computations. Thismay be done by means of the error or elimination key.

According to the vision is made whereby, upon setting the machine forautomatic total-printing, the computing mechanism will be set forsubtraction, so that, during said printing or typing, the complement ofthe totalwillbe indexed. Then, upon operation of the generaloperator,the complement of the result will be run into the totalizer and thelatter cleared.

Provision' may be made of means whereby actuation of the generaloperator will reset the machine from a condition for total printing to anormal condition.

The total-printing mechanism may include an electric motor, the circuitof which present lnventlon, pro

is closed bya'suitable switch or circuitclo siug .device when themachine is set for,

total-printingh This I motor may also .be utilized at th completion ofsuch total- .,printing to actuate th'egeneral operator.

For this purpose, a clutch device is rendered effective to connect thegeneral operator with the motor, and the circuit is closed through asecond switch or circuit-closer in parallel with thefirst. Uponactuation of the general operator to restore the machine to normalcondition, the motor circuit will be broken at the first switch. At thisstage of the opegation, the movement of the general operator has notbeen completed, but, inas-- much as the second switch was closed at thetime'the general operator was clutched to the motor, the latter will beeffective to return the general operator to its normal posi- -t1on, atwhich time the secondzswitch will be opened and the motor circuitbroken.

Other features and advantages will'here-' tions.

thereof brought into engagement with the pins; depressed. The bars 13will then be advanced in accordance with the digits indexed, such motionbeing transmitted by racks 33, on the bars 13, to pinions 34 having theusual one-way connections with numberwheels or dial-wheels 35.

During the forward movement'of the gen-- eral operator, 'arack 36,forming part.there-- of, rotates an idle gear 37 and a second gear 38 toactuate, by a suitable one-way connection, a square'shaft 39, forming apart of the carryover mechanism, the numberwheels being normallymaintained'in posiagainst suitable toothed wheels 42, secured of thecarry-over operation, the result may be read through a suitablesightopening 43 thecomputer casing 44.

The reciprocation of the general o" erator '21 may be effectedautomatically. ozthis end, by suitable means, not shown, as the carriagepasses .out of the computin zone, a link 45 will be depressed to rock'aiail 46 and thereby withdraw a latch, 47 fromjja position above therear end of a lever The lever 48, when released,;wil l in acounter-clockwise direction, by suitab e means, such as a' spring, notshown, about. its ivot 49, so that its forward end; which over ies a pm50 on a slide 51, will cause depression of the-slide; Such depressionwill rock a lever 52 to lift a trip pin 53 out of the" ath of,a lug Aspring 55 will then ecoine efi'ec'tive'to'shift a ring or member 56, ofwhich 111g 54 forms a part, and a ball 57 will bemoved into positionto-.,clutch a cup 58, fixed on ashaft 59, to a'sleeve or'hub 60,loosely. mounted on said shaft. Said a clockwise direction will causeactuation sleeve or hub "60 issecured to or forms a part of a worm-wheel61, and it will be seen that rotation of the" worm-wheel 61 in of theshaft 59.?-

The rotation of the 'r' 56, relative to the inglmeans effective, willcause contacts 62 and 63 of. conductors 64 and65 to be brought intoengagement, so as to complete circuit through a-source of power 66,a'conductor67 Q universal bar 86 e and a motor 68, substantially asdisclosedin the patent to Frederick A. Hart, No. 1,237,-

will then operate until the circuit isbroken, and, by means of asuitable connection, in-

dicated in general by 69, will rotate a shaft '70 and cause a worm 71thereon to rotate the'worm-wheel 61 in a clockwise direction, and,consequently, the'shaft 59, as long as the clutching means, previous]described,

is'eflcctive. .Such rotation of s aft 59 will effect reciprocation ofthe general operator 900 dated August 21, 1917. The motor 68 21 b meansof a member 72 extending up war 1y into a yoke 73, secured to thegeneral operator.

)VVhen it'is desired to set the machine for subtraction, a subtractionkey, not shown, may be actuated to move'a thrust link or bar 74rearwardly, and,.by means of an arm 75, rock a shaft 76, on which saidarm'is fixed. By this movement of the shaft 7 6, a tooth 77 of ahook-like latch-member 78 will be withdrawn from engagementwith ashoulder formed at the forward end vof a notch 79 in a subtraction bar.80, thereby releasing the latter.

- Upon such release, the subtraction bar nection with anarm 82'on, ashaft 83, will rock the latter; An arm. (fixed on the shaft, willactuate, vbya'ffp a i n a universal about an axis near its ripper-edgelower edge of the ment of :the universal bari '86, the shafts willbeadvan'cedito the position shown in Figure '1. Atithe 1 same time, bysuitable means, not'shown, a ibar' 8 8 will be actuated toldepress theforward. ends of levers 89, and 7 thereby depress the 9 pins. As will be-with will depress,on the' selected bar, the 'pin correspondingto thecomplement, "to

In order to obtain suchresetting of the 9; pins, provision is made o storing linkage, having a'lower bar 90 and an upper .bar 91, and means whereby, uponadva'neemovement of the shafts 18 to the position shown in Figure 1 arms92 on'tfie traction-setting spring 111.

. the two ends move simultaneously. Each on the pendant beneath theposition to actuate the upper bar 91 and therefore depress the Tower bar90, the position of-the lower bar -90 being such that it will not beeffective for resetting purposes unless a pin-bar has been selected andraised to pin-setting" position. The submechamsm is, in general, similarto that shown in the patent to Minton, No; 1,280,065, dated September24, 1918.

Fol-automatic total-printing, provision is made of a special operator 93for each keylever operated by a numeral-key. Each operator 93 has afinger 94 overlying a-pin sponding key-lever, and is normally urgeddownward by means of a spring 96, connected at it upper end to a pin 97on the operator 93, and at its lower end to a lug 98 on a fixed part ofthe frame. Each spring 96 is of sufiicient strength to actuate thecorresponding key-lever, and each oper ator 93 is norma'ly held inraised or ineffective position by suitable means, which may comprise aroll 99 mounted by means of a screw-stud 100 on the operator, and asuitable cam, such as a snail cam 101, normally positioned with its highpoint in engagement with the roll 99, as shown in F ig-.

ure 1.

Each cam 101 is loosely mounted on a shaft 102, and may be actuatedthereby through a v suitable clutch or clutching device, including ashell 103 connected with the a sleeve 104 fixed on the shaft, 3, ball104; whereby the shell and sleeve may be operatively connected, a ringor incmber 105 for controlling the position of the ball, and a spring106 urging the ring 105 in the direction to make fective. Normally, thecontrolling ring 105 is held in position to render the c'utching deviceineffective bymeans of a bell-crank 107, mounted on a fixed pivot 108,and having a hook 109 overlying a lug 110 on the ring 105, thebell-crank 107 being normally urged to effective position by means of aThere are ten of the clutching devices,

and, taken in -order-from -left toright, they control the key-leverscorresponding to the digits from 1 to 97, inclusive and 0, Tc actuatethebell-cranks 107 to release the rings 105 in the correspondingclutchin' devices, Iinkagesare provided, one for'eac bet-crank, each "of,said linkages comprising-a lower ban-112 having at each end an uprightarm 113, pivoted to a horizontal arm of a bell-crank 114, of which thedownwardly-extending arm is pivoted to a bar 115, which serves to makethe bell cranks at bar 112 is provided with a tooth 116 lyingrearwardly-extending arm 117 of the corresponding bell-crank 107. As

16 attachedto the corre-- the clutching device ef-- tending tooth tionof the machine,

herein disclosed, the rear bar 112 has a tooth beneath the left-hand bel-crank,

which controls a clutch for the 1 key, and the other bars 112, taken inorder from back to front, have teeth under the rearwardly-extending armsof the bell-cranks 107 which control the actuation of the numeral types2 to 9, inclusive'and 0 In order to cause printing in a givendenomination of a digit exposed on the corresponding.) number-wheel,each numberwheel is provided with suitable means, such as a snail cam118, which controls the position of a lever 119 having a lug 120 norma1y held in engagement with the'cam by means of a spring 120, attached atone end to the lever 119 ata. point beneath its pivot 121 and connectedat the front of the computer casing 44 to alug 121. The lower end of thelever 119 is connected by 3 means of a link .122 withthe upper end of alever 123 pivoted at 12 1,- and having at its lower end a slot-125, intowhich projects a pin 126 on a rearwardly-extending "link or digitselector 127. Each link 1127 is guided for rectilinear movement by meansof a lug 128 extending downwardly therefrom to rest on the upper surfaceof a shelf 129 and by means of a slotted plate 130, the link normallywhich, it passes.

Each of the links 1274is rovided with a tooth 131, the upper end ofwhich lies immediately below the plane of the lowerresting on the bottomwall; "011 the slot through edges of the bars 112, so that it maybe Tmoved back and forth under said bars as the link 127 is 'movedrearwardly and forwardly. In Figure 2,, the snail cam 118, there shown,is in the position corresponding to a showing of 0 on the attached numher-Wheel, and the corresponding tooth 131 is-shown in position underthe front bar 112, which, by means of its upwardly-ex- 116. is adaptedto release the clutch corresponding to the 0 key-lever to enableoperation of the latter by means of the corresponding operator 93.

nism just described serves merely selecting mechanism, in that the teethcorresponding to the different -number-wheels will be positioned vrespectivel under the links corresponding tqthe digits shown on thenumber-wheels. In-an' ordinary operathemovement of these parts will be'idle.

It will be 1 evident from the foregoing that the mechaas digit- When itis desired to have the total shown 1 1 on the number wheels printedautomatically, a handle 132 on a lever-133 is moved rear wardly to swingthe-leverabout its pivot .1 34, and, by means ofa link 135 pivoted tothe lower end of the ;latter and to an arm 136 fixed on a'shaft 137 atthe rear of the machine, to rockthe shaft to swin a plate or bar 138 incounterrclockwise tion - 144. In order that the arms 143, which are.Figure 1, in which their rear ends engage in notches 141 in arms 142extending downwardly from the levers 11.

At their forward ends, the denominational links 140 are .pivoted todownwardly-extending' arms 143 loosely mounted .on a shaft connecteddirectly with the arms 142, may be associated with the number-wheels inthe reverse order, suitable transposition-means must be provided. Tothis end, the righthand arm 143 is connected by means of a bail 145 withan upwardly-extending arm 146 pivotally mounted on the shaft 144. Thesecond arm142, from the right, is con-' nectedwith an arm 146 by abail-145 lying within the first bail 145. It will be evident that, byproviding a bail for each of the arms 142, connected thereto at one endand at the other end to an np'rightcarm 146, the arrangement of the arms146 will be reversed with reference to the 'arms 142. The arrangement ofthe transposition .bailsis clearly shown in Figures 4 and 5.

llhe"upwardly-extending arms 146 are connected byv suitably-shaped links147 to the upright arms of bell-cranks 148 pivoted on a shaft 149, thehorizontally-extending arms of the bell-cranks 148 being connectedby-suitable links 150 with the rear-ends of normally horizontal levers151, pivoted at their forward ends at 153 in brackets or I ears 154secured .to the lower side of the shelf 129. Each of said levers 151 isprovided with an upwardly-extending finger 155 immediately to-the rearof the slotted plate 130, and each of said fingers 155 is provided witha laterally-extendingpin 156 to engage the lower edge of one of thelinks I -At thev same time that the plate 138-is. shifted to bring thelinks 140 into operative connection with the arms142, an arm 157 on theshaft 137 is swung forwardly, and, by means of an arm 158 fixed on theshaft 76, withdrawsthe latch 78 from the notch 79 in subtraction bar 80,permitting the lat-- ter tobe drawn to the rear by the spring 81. Thecomputing mechanism will then be set for subtraction. Shifting of thehandler,

132 to the rear will also cause a member carried by the link 135, ,butinsulated therefrom, to be shifted from its Figure 3 position to itsFigure 1 position, in which it closes a circuit ,;.through thespring-pressed pins 160 and the motor .68 The motor will then actuatethe sherif and by means of the beveled gears '161 and 162 rotate thehorizontal shaft 163. At its right-hand end the shaft is connectedmember or bell-crank 107 from by a beveled gear (not shown) with abeveledgear 164 on" the lower end of a vertical shaft 165. The shaft 165is geared at its upper end to the shaft 102 by means of a beveled gear166 at the upper end of theshaft meshing with a beveled gear (not shown)on the shaft 102; As brought out more fully in said application, No.665,315, the rotation of the shaft 102, when'actuated, will be in aclockwise direction, as indicate b the arrow in Figure 1.

Upon movement of the riage into the computing zone selected fortypewriter cartotal-printing, the links 10 Will be operated v seriat-imfrom right to left and will select thepin bars 13 seriatim from left toright;

Actuation of links 10 will also serve to actuate the levers 151seriatimfrom left to right i to lift the corresponding links 127. Sincethe reading on each number-Wheel .35 determines the bar 112, which is tobe operated, actuation of each one of the levers 151 will actuate theproper bar 112 and thereby withdraw the hook 109 of the proper latchingen ag'ement with a'lug' 110. The corresponding cam 101 will then beclutched ,to the shaft 10,2 in a manner hereinbefore described, and, asthe high portion of the cam is moved to the right from engagement withthe corresponding roll 99,.the proper actuator 93 will be released tothe action of the spring .96

to cause typing of the proper d1git.' At

the same time the digit is typed, the corresponding pendant 16 willengage the corresponding arm 17 to depress one of the pins f' 14.- Sincethe mac 'ne has been set for subtraction, the. depression of the pins onthe various pin or'rack-bars 1-3 will serve to index the complement ofthe number printed on the work-sheet, and, consequent- 1y, of the numberappearing on the numberwheels' of the register.

Each actuation of a numeral-keywill also operate the typewriterescapement mecha-j nism (not shown), and cause another v 1O to beactuated, so that, after moving the machine into'the computing zone, thevarious digits will be printed automatically and'. thecomplementarynumber set up on the pin bars. I At the end, of suchtotal-print-v ing, the link 45 of the motor-trip mechanism will be.depressed, and, by means hereinbefore described, lift the trip-pin 53out of the path oflthe lug 54. j

The worm gear 61 will then be clutched to the shaft 59 and the generaloperator advanced to run the number indexed on the pin bars into thenumber-wheels35,

and, since the complement. of the total has been indexed on the pin bars, such actuation of the pin bars will subtract the total. from thetotal as shown in the register, thereby clearing the latter. r v

Asthe general operator 21 approache no end of said lever 168 the forwardend of itsmovemen't, a pin 167 thereon will strike the lower end of alever 168 and swing the latter-about its pivot 169, sothat a link l'lflconnecting the upper with the lever 133 at pivot 134 will swing thenormal position, thereby links 140 from the arms themotor circuit at thea point-below its handle 132 to its disconnecting the 142 and breakingpins 160. V ,7

The breaking of the circuit at the contact pins 160 willnot, however,tor, since, at the time the trip-pin 53 was lifted, the motor circuitwas contacts 62 and 63 formingfpart of a branch in parallel-with thatconta' g the contact pins 160. The motor 68 will, therefore, be

actuated until the lug 54 on the ring 56 is.

brou ht into engagement-with the trip-pin 53, therebv unclutching theworm gear 61 from the shaft- 59 and breaking the circuit by separatingthe contacts 62 and 63, therey with the numeral-keys by stopping themotor.

Variations may be resorted to the scope of the invention, and portionsofthe improvements'may'be used without others.
